Replacing components, Please weigh in!

Hi Audiogoners! I’ve been a member here for a long time and lurked in the forums on and off over the years, but this is my first query here so hopefully you’ll go easy on me!

I want to improve the sound quality of my relatively modest stereo analog system. I have two components that I think are weak links in my system and I’d love to hear recommendations on replacement components that will complement what I already have (i.e., I don’t want to make new purchases that outperform the components I am satisfied with). 

Here’s what I’ve got:

1. Project 2 Xperience — turntable
   
2. Dynavector P-75 — phono pre
   
3. Dynavector 17D3 — cartridge
   
4. Meadowlark Audio Kestrel (first generation) — speakers
   
5. Nakamichi RE10 — receiver
   
6. Audioquest King Cobra & MIT cables
   

I think the weakest links in my chain are the Nakamichi RE10 receiver and the Dynavector p-75 phono preamp. Both these components have either a fan or an audible hum that annoy the heck out of me. I want a system that is QUIET. 

First Question — I’ve been seeing a lot of love here for the Herron VTPH-2A, Stanley Chinook, and Allnic H1202. My question is: I want to squeeze the most performance out of my speakers and cart as possible without overshooting — are these preamps going to outperform my speakers and turntable? If you think one of them is a good fit, which one do you think is the best for me?

Second Question — I get really overwhelmed reading about amps b/c I really don’t understand the technology and for me it’s like being an English major in a room full of engineers (I’m the former English major — Audiogon is the room full of engineers)! I am truly a low-information junior audiophile. Can anyone point me in the right direction for amps I should be looking at that will be a good fit for my Meadowlark Kestrels? 

I listen to mostly rock and pop from the 70’s and 80’s on clean, original vinyl. My room is 12.5’ wide x 18.5’ long, with a large archway to another room interrupting the long side (sad space, I know). Ceiling is 7’10”. Does this info help you weigh in? Maybe? 

Thanks for your thoughts, this junior audiophile appreciates them!
